In a drawer in one of our disused labs at work I once found a dozen or so small paper packages of various numbered versions of Alox. All dark reddish-brown to black and consistency ranged from hard wax to hard plastic. Apparently they were once used to seal the glass joints of reaction flasks and condensers.
None of them was 2138, so I figured none was “correct” for bullet lube and didn’t investigate further. The buildings were demolished later on, and I imagine the Alox samples are in a drum at a toxic waste storage site now.
